[Xen-devel] [PATCH v5 11/15] drm/st7586: Remove sending of vblank event

[Thomas Zimmermann <tzimmermann@xxxxxxx>]

The atomic helpers automatically send out fake VBLANK events if no
vblanking has been initialized. Remove the sending code from the
driver.

v4:
        * separate commit from core vblank changes
